How to Set Up Pre-Commit Hooks for Teams Using AI Coding Assistants

AI coding assistants write syntactically correct code most of the time. They are considerably less reliable about respecting your project's import conventions, naming patterns, or type contracts. That gap is exactly what pre-commit hooks close. This is a step-by-step guide to setting up pre-commit hooks for a team that uses AI coding tools. The setup applies to both Python and JavaScript/TypeScri...

I added 10 real developer testimonials to my UI library today — here’s what I learned from early users

Over the last few months I’ve been building Uilora, a component library focused on animation-first UI for modern web apps. Today I crossed a small milestone that felt bigger than I expected: I added 10 developer testimonials to the site. Not fake marketing quotes. Real feedback from people actually using the components. When I started this project I thought the hardest part would be building th...

I Inherited a 40,000-Line Java File. Here's What I Found Inside.

description: A developer's case study of inheriting and refactoring a 40,000-line Java Swing file in a production hospital system — without rewriting it. For six months, one application slowed down my work every single day. Every morning I'd open the hospital management system, wait for it to load, and mutter something unkind under my breath. My colleagues did the same. We blamed the database. W...

4 Engineering Patterns That Cut AI Inference Costs 60–80% Without Touching Output Quality

One of the most common engineering problems I see when teams scale AI from pilot to production: the cloud bill is 5–10× what the pilot suggested it would be. This isn't a coincidence or a billing error. It's the predictable result of pilot conditions not reflecting production conditions — cleaner inputs, smaller volumes, no monitoring overhead, no retry logic, no agent orchestration multiplicatio...

MQTT Broker Selection: HiveMQ vs Mosquitto for Industrial Use

I spent a month running both HiveMQ and Mosquitto in a production IoT setup with 2,500 endpoints. The difference between them wasn't in the marketing material , it was in the logs, the failed connections, and the way they handled message floods. HiveMQ had a clean dashboard and enterprise support. Mosquitto had a simpler config and less overhead. Neither was perfect. Both had gotchas that weren't ...

I Built a VS Code Extension That Validates VAST XML as You Type

If you work in ad tech you've probably seen VAST XML. It's the IAB standard that carries every video and CTV ad impression: the tag that tells a player what to show, where to fire tracking pixels, and how to handle wrappers. $30B+ in annual US ad spend runs through it. It's also surprisingly easy to ship a broken one. The spec is six versions deep (2.0 through 4.3), touches several other standa...
